TRANSFORM

 

Description: This function allows the user to move or rotate a selected surface either locally or globally.

 

Usage:

 

1.  DSI prompts:

>          CREATE LOCAL COORDINATES

>          PICK NODE/PT FOR ORIGIN

DSI prompts the user to create a local coordinate system.  The user also has the option to select the global coordinate system.  (Refer to Local Coordinate System, Section 2.16, for a thorough explanation of this procedure.)

 

2.  Once the desired coordinate system has been defined, DSI prompts:

>           MOVE OR ROTATE (M/R)

?       MOVE

>   ENTER U, V, W INCREMENTS

•        i.e. /0,0,1000/.  This will transform the selected surface(s) 1000 units along the W-axis.

ROTATE

•        If ROTATE is entered, enter angle increment (right hand rule) about the W-axis. The remaining commands are the same as the MOVE option.

ABORT

•     User will now be prompted to select the surface to be transformed.

 

3.  DSI prompts the user to select surfaces to transform.  The user also has the option to select AGAIN or REVERSE to repeat the rotation or movement.  Once the desired surfaces are selected, enter DONE to continue.
